Patented Jan. 30, 1951 UNITED STATES PATENT OFFICE GOLF-SHOE CALK WRENCH Clare R. Daniels, Milwaukee, Wis. Application August 29, 1947, Serial No. 771,326 2l claims. (c1. 31-90) The present invention relates generally to irnprovements in devices for applying and removing shoevsole dalks, and relates more specifically to various improvements in the construction and operation of wrenches for eiecting attachment and removal of golf shoe calks or the like.

The primary object of this invention is to provide an improved calk manipulating wrench unit which is simple and compact in construction, iiexible in its adaptations, and highly eil'ective in use.

Many types of athletic shoes are provided with sole calks adapted to prevent foot slippage, and these calks as applied to golfers shoes have been relatively standardized and are made removable or"`detachable, so that they may be readily replaced whenever desired. The present standard golf shoe calk comprises a metal conical spike formed integral with one side of a relatively wide base ilange having an integral threaded projection extending centrally away from its opposite side and adapted to coact with an internally threaded bushing firmly secured to the sole of the shoe. The base lianges are usually of circular or' polygonal shape; and each of these ilanges is provided with diametrically opposite socket openings dr ats disposed on opposite sides of the protruding spike, and adapted to coact with similarly spaced pins of a Spanner wrench which is opeiable to apply and remove the calk. Since the span or spacing of the flats or socket openings of the calks produced by different manufacturers, varies` slightly, it is necessary at present, to utilize a special Spanner wrench for each different type o fqcalk. Then too, the spanner pins of the present wrenches are not conveniently renewable, and since these pins are frequently bent or broken by rabuse or excessive wear, it is extremely desirable A*trhave the pins readily replaceable and to also have spare pins constantly available. The prior wrench assemblages do not make provision for such convenient renewal, and are moreover rather bulky thus making it diffcult to carry them in limited spaces.

It is therefore a more specificl object of my present invention to provide an improved wrench assemblage especially adapted for manipulation of such relatively standardized golf shoe calks,r

and which obviates all oi the above mentioned difculties and objections.

vAnother specific object of the present invention is to provide an improved Spanner wrench which may be readily set or adjusted to accommodate different socket opening Spacings of various types A further speciiio object of this invention is to provide an improved replaceable pin type of calkwrench, wherein extra pins may be kept constantly available for replacement, within the unit.

Still another specic object of the invention isto provide an improved calk wrench unit Which may be partially dismantled and arranged in compact unitary condition, but which may be conveniently assembled ready for normal use.

An additional specific object of my invention is to provide an improved collet type of Spannery wrench especially adapted for applying and re:

moving golfers shoe calks.' and which may be manufactured and sold for diverse uses, at mody erate cost. 1

These and other specic objects and advantages of the present invention will be apparent from the following detailed description.

-A clear conception of the several features constituting my present improvement, and of thel specific construction and mode of utilizing golf shoe calk wrenches embodying the invention, may.

be had by referring to the drawing accompanying and forming a part of this specication, wherein like reference characters designate the same or similar parts in the Various views.A

Fig. 1 is a fragmentary part sectional perspec` I wrench spindle for compact storage or transpor- While the invention has been shown and de- Referring to the drawing, the improved collet,v wrench shown therein, comprises in general a main hollow spindle E having a transverse through; opening 1 near one end and being provided with` a tapered head 8 and parallel saw Icuts 9 at itsopposite end, while its medial portion has external screw threads I!! formed thereon; an externally knurled sleeve or collar II embracing the spindle 6 and having internal screw threads near one end coacting with the screw threads I of the spindle, while its opposite internal end portion is provided with a tapered bore I3 which is cooperable with the four resilient jaws I2 formed on the spindle head 81 by theintersectingsaw cuts 9, to press these-'jaws I2 inwardly; av pair of cylindrical spanner pins" I4 adapted to cooperate with or to be inserted within diametrically opposite cylindrical recesses or sets of holes I5, I5 formed in the spindle head 8 at the several. saw cuts 9; and a wrench manipulating cross-bar or handle I6 adapted to snugly engage the spindle openings 'I during normal use, butbeingins'ertible within the central spindle bore I'I and adapted to be retained therein by screw threads I8 when not in use.

The vmain spindle 8' is preferably for-med'ofnoncorrosive relatively resilientfmetal so that the jaws I2 willalways be outwardly biased, and while only two sets of parallelV grooves orl vsaw cuts 9 have been shown, more sets of these grooves andresultant jaws i2 may be provided. The spacing ofthe diametrically opposite sets of recesses or pin 'receiving holes I5, I5 is such that one set of pins I4 will fit the pin receiving flats or sockets Illof one type of cal-k 20 as shown in Fig. 3, Where-as the other set of pins coacting with the recesses I5 will be spaced aparta greater or less er distance so as to t vthe corresponding Hats or sockets of another type of calk. Each of these metal calks 28 has a tapered spike 2| formed integralV with one side of a base disc 22 in` which theflats or sockets I9 are formed; andy also has a central screw threaded projection 24 formed integral with the opposite side of its base disc, and adapted for coaction with the internal screw threads of metallic receiving bushings 25 firmly attached to a shoe sole 25, fragments of which arershown in section in Fi-g. 3.

The spanner pins I4 are preferably Aformed of suitable metal, and are adapted to Yrather loosely fit the spindle holes I5', I5 when the collar lI has been withdrawn and the resilient jaws- I2 are spread apart, but are also 'capable oi'being clamped' firmly against the spindle head 8 when the collar II is screwedtoward the headed end of the spindle E. Since these pins I 4 wear rather rapidly, and frequently break off, yit is desirable to provide several spare pins, and in order to permit such spare pins I4 toY be conveniently stored', Iha've provided the actuating handle I 6 with a central bore or pocket 21 at its end remotefrom the screw threads I8, and have also provided a closure or pin confining screw 28y for the pocket 2'I, as clearly shown in Fig. 3. The externallythreaded end of theV cross-bar or handle IIS may furthermore be provided with an' externally'serrated knob 29 for facilitating'insertion andremoval relative to the central spindle bore 'I1 as depicted in Fig.'2, so that an exceedingly compact wrenchunit free from external projections when not in use, is provided; Y I

When the improvedv wrenchl assemblage is stored away or being transported, the various parts may be compactly positioned with a pair`A of pins Id inserted within a selected yset of VtheY 70l receiving holes I5, |51 and with the handle-i6 and-its extra pins I4, confined within"the1sp indle bore Il, as in Fig. 2. In orderV to place the as-l semblage in condition fornormaluse, it is' only the spindle 6, to thereafter withdraw the handle I6 bodily from within the spindle bore I'I, and to nally insert the handle within the transverse spindle end openings I as in Fig. 3. The collar I I Should then be rotated to cause the screw threads IU to urge the tapered bore i3 against the jaws I2 so as to force these jaws inwardly into iirm clamping engagement with the pins I4, whereupon these. pins maybe appliedeitherto the Yflats of a"calk 2,0 having@ polygonal base disc '22, or to the sockets I9 f a calk 20 having a circular base disc 22 as illustrated in Fig. 3. The calk 28 may thereafter be either attached to or removed from a Ythreaded''receiving bushing 25 by merely turning the spindle 6 in the proper direction With the "aid ofthe transverse handle I6; and subsequent restoration of the tool to the condition shown in Fig. 2 may be just as readily effected.

From the foregoing detailed description of a typical embodiment of the invention, it should be apparent that I have in fact provided an improved collet wrench especially applicable to golf shoe calks 20, and which is simple and compact in construction, flexibleY in its adaptations, and highly efficient in use. The collar I I coacts with the spindle jaws I2 to firmly but detachably clamp the pins I4 within the holes I5, I5', 'and by selecting the proper set of receiving holes,- these pins I4 ymay be caused to properly cooperate with diverse types of c'alks 20 having either perforated or polygonal base flanges or discs. 22. The removability of the cross-bar or handle VI6 and 'the provisionof the spindle bore I'I and. screwv threads I8 whereby the handle may be concealed within the mainspindle 6 as in Fig. 2, make the dismantled unit. extremely compact for storage. andcarrying purposes; and the provision ofstor-v age space for spare pinsl I4 within the handlev thereby providing a durable wrench'unit. The

invention has ngone,into-highlyY satisfactory com.- mercial use; and it is not necessarily confinedfto the-golfing field but may valso be advantageously applied for other purposes.

Itshould be understood that it torlimit thisrinvention t'o theexact details ofcon sruction` orY to the precise mode of use, herein:l

shown and' described, forvarious modificationsA within the scope ofthe appended claims, may' occur toy persons skilledin th'e art; and itis-falso contemplated that specific-descriptive' terms used herein be given the broadest possible interpretation consistent with lthe disclosure.
